Professional Applications & Engineering Value

This M18 hex head screw delivers critical engineering solutions where corrosion resistance and high tensile strength are paramount. Manufactured from 18-8 stainless steel, it withstands corrosive environments in marine, chemical processing, and outdoor construction applications. The coarse metric thread (M18 x 2.5mm) ensures rapid assembly and disassembly while maintaining Class 6g thread fit precision. The partially threaded 120mm length provides optimal unthreaded shank strength where shear forces are concentrated, making these DIN 931 compliant fasteners ideal for structural connections, machinery frames, and heavy equipment where vibration resistance and long-term reliability are essential.

Specification Summary & Compliance

This metric hex head screw features M18 x 2.5mm coarse threads with Class 6g thread fit tolerance per ISO standards. The 120mm length includes a 42mm minimum threaded section. Manufacturing complies with DIN 931 specifications for dimensional accuracy and mechanical properties. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting international environmental and safety regulations for industrial components.
